Abstract (en)
A take-up spool which comprises two identical components having respective elongate portions (11, 11A) which cooperate in side-by-side parallel relationship to form the core of the spool, the two components carrying two pairs of interengaging locking parts (13, 14) at the opposite ends of the elongate core portions (11, 11A), which locking parts (13, 14) are released by a relative unlocking movement of the two components which simultaneously brings about a relative bodily movement of the two elongate portions (11, 11A), which results in a reduction in the cross-sectional size of the core.
